Slide 2

Osmosis ­ The NET movement of watermolecules from a region of higher waterpotential to a region of lower water potentialacross a partially permeable membrane. Likediffusion it will stop when the water potential isthe same on both sides.…read more

Slide 3

For example, here the net movement would be the water molecules (theblue circles) from the left to the right as there is a higher water potential onthe left.…read more

Slide 4

What does water potential mean? Water potential () is measured in KiloPascals (kPA) and is a measure of the concentration of water molecules to move freely in solution.…read more

Slide 5

For example...... If you were to dissolve sugar (solute) in a glass of water (solvent) to form a solution, the water potential would be lower than in a glass of distilled water. This is because many of the water molecules in the solution would be clustered around the sugar molecules, this lowers the concentration of water molecules that are free to move.…read more

Slide 6

Osmosis in animal cells. There is more sugar in the solution (hypertonic) There is less remember when you are sugar in the hyper you have lots of cell then in the sugar solution Water enters The cell shrivels the cell as all the water is through lot through osmosis and it osmosis. It is bursts. It is crenated. haemolysed.…read more
